RADAMEL FALCAO wants to leave Monaco just a couple of months after joining from Atletico Madrid as he faces his salary being cut in half by French tax laws.

And Chelsea and Manchester City are on alert after concerns arose about the lack of competitive balance in the French league brought about by Monaco's status as a principality.

Monaco splashed out £51m on Falcao earlier this summer as they made a statement of intent.

But thé nouveaux-riche side are at risk of having to offload their prize asset or they may have to pay a £75m fine.

Currently, Falcao is getting a massive tax-free salary, a luxury that hasn't been afforded to the other Ligue 1 outfits.

But reports in Spain suggest that the player's £12m salary could be effectively cut in half by changes proposed by Francois Hollande's regime.

So the tax advantage that Monaco is considered as unfair

French journalist Cyrille Haddouche, who works for Le Figaro paper, was quoted by the BBC, as saying: "The advantage is huge in being able to convince huge players like Falcao to move to the club.

"So the tax advantage that Monaco is considered as unfair [by the clubs], especially in a period of economic difficulties for all clubs except Paris Saint-Germain.

"For example, former winners of the league, Lyon and Lille, must now sell players in order to reach break even."

Monaco have sinced move to deny that Falcao will need to be sold, saying on their offical Twitter account: "The club categorically deny rumours about a sale of Falcao.

"As a reminder, the Colombian attacker has signed with ASMFC for five years."

But according to AS, Falcao feels "let down" by Monaco owner, Russian multimillionaire Dmitry Rybolovlev, and believes he was recruited to the club under false pretenses after only moving to France because the club could pay him over £4m more than his next best offer.

The paper goes on to suggest that the player may have already been offered to Real Madrid, with Florentino Perez declining the option to bring the Colombian back to Spain as he focusses on his pursuit of Tottenham's Gareth Bale.

And that could leave the door open for Chelsea or Manchester City to make a move, with Arsenal and Manchester United both thought to also be monitoring the situation closely given the failure to prize Luis Suarez from Liverpool and the uncertainty continuing to surround Wayne Rooney, respectively.
